Expanding the Synthesis Field of High‐Silica Zeolites

15. Juli 2020 von

Angewandte Chemie, EarlyView.Zeolite synthesis in an acidic medium is investigated. The isoelectric point (IEP) of the silica source is found to be the critical factor controlling the zeolite formation under acidic conditions. The zeolite crystalizes solely at a pH above the IEP when the silica particles are negatively charged. Abstract Aluminosilicate zeolites are … [Weiterlesen...] Infos zum Plugin Expanding the Synthesis Field of High‐Silica Zeolites

Copper‐Catalyzed Deaminative Difluoromethylation

15. Juli 2020 von

Angewandte Chemie, EarlyView.An efficient Cu‐catalyzed approach is reported that enables the conversion of alkyl pyridinium salts, which can be readily synthesized from the corresponding alkyl amines, to their alkyl difluoromethane analogues. This method can be applied to the late‐stage modification of complex amino‐containing pharmaceuticals. Abstract The … [Weiterlesen...] Infos zum Plugin Copper‐Catalyzed Deaminative Difluoromethylation

N‐Annulated Perylene Bisimides to Bias the Differentiation of Metastable Supramolecular Assemblies into J‐ and H‐Aggregates

15. Juli 2020 von

Angewandte Chemie, EarlyView.The distinctive self‐assembling features of N‐annulated perylene bisimides 1 and 2 are reported. Diester 1 , with no H‐bonding interaction operating, affords stable cooperative J‐type supramolecular polymers. The incorporation of amide functional groups in 2 results in a stimulating differentiation with several pathways … [Weiterlesen...] Infos zum Plugin N‐Annulated Perylene Bisimides to Bias the Differentiation of Metastable Supramolecular Assemblies into J‐ and H‐Aggregates

Thermochromic meltable materials with „reverse spin transition“ controlled by chemical design

15. Juli 2020 von

Angewandte Chemie, Accepted Article.We report a series of meltable Fe II complexes, which, depending on the length of aliphatic chains, display abrupt “forward” low‐spin to high‐spin transition or unprecedented melting‐triggered “reverse” high‐spin to low‐spin transition on temperature rise. The “reverse spin … [Weiterlesen...] Infos zum Plugin Thermochromic meltable materials with „reverse spin transition“ controlled by chemical design

Mediated Drug Release from Nano‐Vehicles by Black Phosphorus Quantum Dots for Efficient Therapy of Chronic Obstructive Pulmonary Disease

15. Juli 2020 von

Angewandte Chemie, Accepted Article.Chronic obstructive pulmonary disease (COPD) is an intractable disease involving a sticky mucus layer and nano‐agents with the mucus‐penetrating capability offer a new way to deliver drugs therapeutically.  However, drug release from nano‐vehicles requires optimization in order to enhance the therapeutic effects of COPD … [Weiterlesen...] Infos zum Plugin Mediated Drug Release from Nano‐Vehicles by Black Phosphorus Quantum Dots for Efficient Therapy of Chronic Obstructive Pulmonary Disease
